Abstract
An energy-saving and environment-friendly cupola furnace comprises a furnace body, a molten metal outlet, a slag outlet, a waste gas outlet, a waste gas treatment device and an energy recovery device. At least two series-connected bells are arranged on the upper portion of a material inlet of the furnace body in sequential connection mode, and each bell comprises a hopper, a bell valve and a bell valve rod of the bell valve. Each bell valve is designed to be of a pillar-shaped structure with the upper end diameter smaller than the lower end diameter, a valve surface is arranged on the lateral surface of the bell valve, and each bell valve rod is fixedly connected with the upper portion of each bell valve. In the working condition of bell blanking, the bell rods are driven by a driving mechanism to jack the bells away from material outlets of the hoppers; and in the working condition of bell feeding, the bell rods are driven by the driving mechanism to pull the bells to be against the material outlets of the hoppers. During working, the bells are closed, raw materials are filled into the hoppers sequentially, the bells are opened from top to bottom sequentially through the driving mechanism to feed materials, the former bell is closed when the last bell is opened, and the operation is simple. Waste gases can serve as hot sources and fuels of preheated inlet air only after entering the waste gas treatment device through the waste gas outlet and a pipe of the waste gas outlet to be dedusted. The energy-saving and environment-friendly cupola furnace has the advantages of being simple in structure, low in cost, easy to process and operate and safe and reliable to use.
Description
Technical field
The present invention relates to the metallurgical casting installations technical field of smelting metal, particularly relate to a kind of furnace cupola of energy-conserving and environment-protective.
Background technology
Casting is one of important foundation industry of machine building industry, occupies considerable status in the national economic development.In China's casting industry, have more than 28000 foundry enterprise, be the first big country of world production cast article.And China's major part foundry enterprise is all use traditional cold blast cupola to carry out melting.
In prior art, furnace cupola is one of visual plant of deposite metal in metallurgical casting production technology, after metal derby or ingot melts being become molten metal by furnace cupola, in order to casting metal foundry goods.Furnace cupola is a kind of smelting furnace of vertical cylinder-like structure, includes body of heater, molten metal outlet, slag notch, exhaust vent etc.Furnace cupola is mainly used for the production of the metal castings such as cast iron, also can in order to coordinate pneumatic steelmaking.Furnace cupola claims furnace cupola because of its furnace roof opening upwards.
Since 20th century, the structure of furnace cupola and smelting technology thereof have had and have developed on a large scale very much, mainly contain: 1. many exhaust outlets blast cupola furnace, this be for strengthening ash content is high, the burning of lumpiness is little, intensity is low lean coke and the little Cupola of two or more rows that occurs, the air port gross area only accounts for about 5% of sectional area in stove, tuyere area stove footpath reduces, and expands gradually to fusion zone.2. two outlet opening wide pitch blast cupola furnace, its tuyere pitch is than normally large 2 ~ 3 times, and between 500 ~ 900 millimeters, often arranging air intake can be supplied by independent bellows, also can be provided by total bellows.3. Duplex melting of cupola and induction furnace melting, can give full play to the melting capacity of furnace cupola excellence and the good overheated ability of electric furnace.4. improve wind pushing temperature, or increase the oxygen content in air-supply.
But, the equal ubiquity of this kind of furnace cupola of the prior art following problem: the high-temp waste gas of fusion process upwards flows out body of heater from furnace roof opening along the inner chamber of body of heater, wherein some is that directly discharge passes into air, and some after dust pelletizing system dedusting, is disposed to air according to the requirement of environmental protection again.Thus casting place surrounding enviroment are in the misty state of ash throughout the year.And its coke ratio is high, it is large to pollute, be the rich and influential family of power consumption and blowdown, this, more and more high current of environmental requirement, seriously constrains development and the growth of foundry industry.Further, high-temp waste gas, except not processing except clean dust completely, also contains CO
2, SO
2, N
2, and the pernicious gas such as a large amount of CO of producing because of coke incomplete combustion, this is not only to environment, and cause CO poisoning to the operating personnel in casting place and damage healthy, even therefore, death occurs, this has become casting industry hard nut to crack urgently to be resolved hurrily for a long time.Meanwhile, the discharge of high-temp waste gas also results in a large amount of hot loss of energy, and combustible a large amount of CO, a small amount of H
2and CH
4deng the energy loss of combustible.
(number of patent application is Chinese invention patent application: 201110359709.7) disclose one " charging system of furnace cupola ", the charging system of the furnace cupola of this patent application comprises feeding device and material guide device.Material guide device has two, is separately positioned on the front side of corresponding furnace cupola, and two material guide devices are divided into left side material guide device and right side material guide device by the difference of the right position residing for it.Two material guide devices include support machine component and material guide structure part, and two material guide devices are relative to the sagittal vertical guide almost symmetry of between them.Above-mentioned material guide structure part comprises deflector chute, and the opening of deflector chute is towards upper rear, and the position, front end of deflector chute is fixedly connected on support, and deflector chute entirety is arranged according to angled manner low after front height.The guide rail of feeding device along left and right to the top of front and back to middle part being horizontally set on two material guide devices, thus makes hopper can carry out blanking above any one in two material guide devices, can meet two furnace cupolas and use.High-temp waste gas is avoided upwards to flow out body of heater from furnace roof opening along the inner chamber of body of heater by its material guide device by reaching in outside material importing furnace cupola thus.
But the charging system structure of this furnace cupola is more complicated, it controls and operates also more complicated, and still fails to solve a large amount of hot loss of energy, and combustible a large amount of CO, a small amount of H
2and CH
4deng the energy loss problem of combustible.
